Abstract

EN UN SISTEMA DE NAVEGACION, CON UN SENSOR DE CAMPO MAGNETICO, INSTALADO EN UN VEHICULO, PARA DETERMINAR LA DIRECCION, ASI COMO, ADICIONALMENTE, PARA PROPORCIONAR DATOS LOCALES, SE CALCULA EL FALLO ANGULAR DE LA INSTALACION DEL SENSOR MAGNETICO DE LA SIGUIENTE FORMA: SE CALCULA LA DIFERENCIA DEL VALOR REAL MEDIDO DE LA DIRECCION Y DEL VALOR PRESCRITO, CALCULADO A PARTIR DE LOS DATOS LOCALES CONOCIDOS. EN LO QUE RESPECTA A LA DIRECCION, DEL VALOR DESEADO, SE ACUMULA EN LA PERTINENTE MEMORIA DEL SECTOR, PREVIA EXTRACCION DEL VALOR MEDIO. SI TODOS LOS VALORES MEDIOS EN TODOS LAS MEMORIAS SECTORIALES COINCIDEN SIGNIFICATIVAMENTE, SE CALCULA UN VALOR MEDIO GENERAL Y SE UTILIZA COMO FALLO DE GIRO PARA LA CORRECCION DE LA MEDIDA DE LA DIRECCION.
